In my application I have an activity in which you can pin in map a location based on the address you type in edittext or you can just move the pin that it appears in the onMapReady function.
My activity's layout has the fragment that shows the map, a button to return information about position of the pin in the previous activity and an edit text that after typing an address and press button, the previous pin that was on the map is being removed and a new one appears with the location you typed (if it exists).
-- This is my onMapReady function that has a listener in the search button and initialize the pin and the functions that takes pin location after you drag it:
@Override
public void onMapReady(final GoogleMap map) {
map.setMyLocationEnabled(true);
map.moveCamera(CameraUpdateFactory.newLatLngZoom(position, 13));
CameraUpdate zoom = CameraUpdateFactory.zoomTo(15);
map.animateCamera(zoom);
map.addMarker(new MarkerOptions()
.title("Shop")
.snippet("Is this the right location?")
.position(position))
.setDraggable(true);
// map.setInfoWindowAdapter(new PopupAdapter(getLayoutInflater()));
map.setOnInfoWindowClickListener(this);
map.setOnMarkerDragListener(this);
ImageButton search = (ImageButton) findViewById(R.id.search);
final EditText searchaddress = (EditText) findViewById(R.id.locationsearch);
final int[] numAttempts = {0};
search.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//FIND LOCATION BY ADDRESS
Geocoder geoCoder = new Geocoder(MapsActivity.this.getApplicationContext(), Locale.getDefault());
// try {
if (searchaddress.getText().toString() != null && !searchaddress.getText().toString().isEmpty()) {
try {
List<Address> geoResults = geoCoder.getFromLocationName(searchaddress.getText().toString(), 1);
if (geoResults != null) {
// do {
// geoResults = geoCoder.getFromLocationName(searchaddress.getText().toString(), 1);
// numAttempts[0] = numAttempts[0] + 1;
// }
// while (geoResults.size() == 0 || numAttempts[0] == 5);
if (geoResults.size() > 0) {
Address addr = geoResults.get(0);
if (!addr.toString().isEmpty()) {
double latitude = addr.getLatitude();
double longitude = addr.getLongitude();
position = new LatLng(latitude, longitude);
map.moveCamera(CameraUpdateFactory.newLatLngZoom(position, 13));
CameraUpdate zoom = CameraUpdateFactory.zoomTo(15);
map.animateCamera(zoom);
//Marker marker = null;
map.clear();
//marker.setPosition(position);
map.addMarker(new MarkerOptions()
.title("Shop")
.snippet("Is this the right location?")
.position(position))
.setDraggable(true);
// map.setInfoWindowAdapter(new PopupAdapter(getLayoutInflater()));
map.setOnInfoWindowClickListener(MapsActivity.this);
map.setOnMarkerDragListener(MapsActivity.this);
} else {
Toast.makeText(getApplicationContext(), "Addr is empty!", Toast.LENGTH_LONG).show();
}
} else {
Toast.makeText(getApplicationContext(), "Wrong address. Please try another one! :" + geoResults.size() + "!", Toast.LENGTH_LONG).show();
}
}
else {
Toast.makeText(getApplicationContext(), "Null address!", Toast.LENGTH_LONG).show();
}
}catch(Exception e) {
Log.e("GEOCODER", e.getMessage(), e);
}
} else {
Toast.makeText(getApplicationContext(), "Please enter an address!", Toast.LENGTH_LONG).show();
}
}
});
}
@Override
public void onInfoWindowClick(Marker marker) {
//Toast.makeText(this, marker.getTitle(), Toast.LENGTH_LONG).show();
}
@Override
public void onMarkerDragStart(Marker marker) {
LatLng position0 = marker.getPosition();
Log.d(getClass().getSimpleName(), String.format("Drag from %f:%f",
position0.latitude,
position0.longitude));
}
@Override
public void onMarkerDrag(Marker marker) {
LatLng position0 = marker.getPosition();
Log.d(getClass().getSimpleName(),
String.format("Dragging to %f:%f", position0.latitude,
position0.longitude));
}
@Override
public void onMarkerDragEnd(Marker marker) {
position = marker.getPosition();
Log.d(getClass().getSimpleName(), String.format("Dragged to %f:%f",
position.latitude,
position.longitude));
}
Till a few days ago, I could display a pin from the location that the user typed in the edit text with exact the above code. Now, for unknown reason, I can't do this anymore with the exact same code.
Always it appears the toast about 'Wrong Address. Please try another one!' even though the address I type in edit text exists, the size of the geoResults is always 0 and no exception is occured in Logcat
-- When I remove from comments the do-while part, the exceptioms in logcat are the below:

I don't know what this thing in the parenthesis is but my package name is guide_me_for_all not uide_me_for_all. (in case it has something to do with this)
If someone could help me find what does all the above mean, I would be really grateful.
Update after correcting the above code: Code to return position from the class to the previous activity (UNSOLVED - Always getting NULL Value):
In the class:
@Override
protected void onPostExecute(LatLng result) {
Log.i("GEOCODE", result.toString());
Intent i = new Intent(this.mainContxt , MapsActivity.class );
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.putExtra( "latlng" , result );
this.mainContxt.startActivity(i);
super.onPostExecute(result);
}
In onCreate of the MapsActivity, I have this:
if (getIntent() != null) {
Intent intent = getIntent();null){
position_from_address = intent.getStringExtra("latlng");
}
And after that in the onClickListener of search button of my activity, I am getting the position like this:
if (position_from_address != null){
String[] latlong = position_from_address.split(",");
double latitude = Double.parseDouble(latlong[0]);
double longitude = Double.parseDouble(latlong[1]);
position = new LatLng(latitude, longitude);
A problem might be that the lookup is not done in a background thread, try and copy-paste the code from my answer here: Google Geocoder service is unavaliable (Coordinates to address)
Then run new GetAddressPositionTask().execute("someAddress") and see what happens.
Passing a context to the AsyncTask:
Add a constructor:
public class GetAddressPositionTask extends
AsyncTask<String, Integer, LatLng> {
private Context context;
public GetAddressPositionTask(Context context) {
this.context = context;
}
// .. rest of the code here
}
Usage:
GetAddressPositionTask(context).execute("someAddress")
Where context is either getApplicationContext() or getActivity().getApplicationContext() if called from fragment.
Regarding the nullpointer:
Not 100% clear where you are getting the nullpointer, but you should be able to do like this:
// in onPostExecute
i.putParcelable("latlng", result);
and in MapsActivity
LatLng position = (getIntent() != null) ? getParcelable("latlng") : null;
Another place of concern is this.mainContxt. Simply do YourActivity.this instead or getApplicationContext(). If you are in a Fragment then do Context context = getActivity() and ensure that it is not null.
